Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to a charging pile with energy storage function and a control and regulation system. Background Art

[0002] A charging pile is a device that replenishes electricity for electric vehicles. Its function is similar to that of a gas pump in a gas station. It can be fixed on the ground or on a wall and installed in public buildings (charging stations, shopping malls, public parking lots, etc.) and residential parking lots. It can charge various types of electric vehicles according to the adjusted voltage and current.

[0003] With the increasing awareness of environmental protection and sustainable travel, electric vehicles have gradually become a trend in the automotive industry. The demand for charging electric vehicles is growing rapidly, so an effective charging control system is needed to meet these needs. The charging control system of the charging pile is a complex system designed to manage, monitor and optimize the charging process of electric vehicles.

[0004] For example, a charging pile charging control system proposed in 202311038439.9 regularly analyzes the discrete degree of power correction coefficients of all power grids through an evaluation module, sorts all power grids based on the discrete degree of power correction coefficients, generates a power grid sorting table, and sends the power grid sorting table to the charging station administrator. The charging station administrator selects the access order of the charging station power grid according to the sorting table. The control system avoids excessive pressure on the charging pile, reduces the charging burden, and enables the charging station to select the optimal power grid for access, effectively ensuring the charging stability of the charging pile.

[0005] However, the charging piles in the prior art can only charge new energy vehicles with the same type of voltage requirements and convert AC power into DC power for use. In addition, there are often delays or misoperations in the intelligent control process due to unclear module division, and data parameter display abnormalities during use, resulting in slow charging speed. Therefore, a charging pile with energy storage function and a control and adjustment system are proposed to solve the above problems. Summary of the invention
